Quick Answer: Why Gypsum Is Added In Cement 2 ...

How much gypsum is added to cement? To achieve the desired setting qualities in the finished product, a quantity (2–8%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker, and the mixture is finely ground to form the finished cement powder. This is achieved in a cement mill.

Performance of Slag Cement with Portland‐limestone …

Type IL : Portland Clinker is ground in ball mills together with ~8% gypsum and 10-13% raw limestoneto make the finished cement. (gypsum levels need to be optimized) Because limestone is softer than clinker, it grinds preferentially, so the cement needs to be ground finer so the clinker component is of equal fineness to get the same strength
